采用热压形变工艺，成功地制备出了具有择优取向的高强度高韧性云母微晶玻璃。用三点弯曲法和单边切口梁（ＳＥＮＢ）法在不同工艺条件下对微晶玻璃的抗弯强度和断裂韧度进行了测定。结果表明：在热压形变过程中，玻璃相发生粘性流动，云母晶体随之转动并产生择优取向，增强了对平行于热压方向的裂纹的偏转和分叉作用，材料的力学性能得到显著提高。基础玻璃在９５０℃晶化３ｈ并经１０００℃热压形变处理后，所得的云母微晶玻璃在热压方向上的抗弯强度和断裂韧度分别可达３９０ＭＰａ和２．９２ＭＰａ·ｍ１／２，比热压前提高了２倍多。
Hot pressing deformation process was used to successfully prepare high strength and high toughness mica glass with preferred orientation. The flexural strength and fracture toughness of glass-ceramics were measured by three-point bending method and single-side notch beam (SENB) method under different technological conditions. The results show that during the hot deformation process, the glass phase is viscous flow and the mica crystal turns along with the preferential orientation, which enhances the deflection and bifurcation of the crack parallel to the hot pressing direction. The mechanical properties of the material are significantly improved . After the base glass was crystallized at 950 ℃ for 3h and hot-pressed at 1000 ℃, the flexural strength and fracture toughness of the obtained mica glass-ceramic in the hot-pressing direction were up to 390MPa and 2.92MPa · m1 / 2 respectively, More than 2 times more than before hot pressing.
